Tengzhou Zhongkepu is a professional manufacturer of ethylene glycol detectors, ethylene glycol purity gas chromatographs, and portable chromatography equipment. The equipment produced meets national standards and is favored and recognized by users in the market. The following are the specificationsGC2020Detailed dissection of the purity price, usage method, instrument structure, and service system of ethylene glycol analyzed by gas chromatography:

【 Product Name 】 Gas Chromatography Analysis of Ethylene Glycol Purity

【 Product Properties 】 Ethylene glycol, also known as "ethylene glycol"“1,2-Ethylene glycol, abbreviated asEGThe chemical formula is(CH2OH)2It is the simplest diol. Ethylene glycol is a colorless, odorless, sweet tasting liquid that is toxic to animals. The lethal dose for humans is approximately1.6 g/kgEthylene glycol is miscible with water and acetone, but its solubility in ethers is relatively low. Used as a solvent, antifreeze agent, and raw material for synthesizing polyester.

【Installation requirements】Basic operating requirements for instruments

1Power requirements:

Voltage: 220 ± 10%

Frequency: 50 ± 0.5Hz

Power: ≥ 3000W

Grounding requirement resistance: ＜ 0.1Ω

2Gas source requirements:

Nitrogen: 99.995%

Hydrogen: 99.995%

Air: dry and oil-free

3Basic operating requirements for hydrogen flame ionization detector (FID)

Carrier gas: flow rate 50ml/min (30-80 ml/min)

Hydrogen gas: flow rate 30ml/min (25-40 ml/min)

Air flow rate: 350 ml/min (250-500 ml/min)

4Basic operating requirements for thermal conductivity detector (TCD)

Before starting up, the carrier gas should be supplied for 30 minutes with a flow rate of 50ml/min, and then the machine should be turned on for heating

Flow correction, two outlet flow deviation ≤ 1%

According to the analysis requirements, set the size of the bridge flow value

When using nitrogen as the carrier gas, the bridge flow should be appropriately reduced compared to hydrogen as the carrier gas

5Electronic Capture Detector(ECD)Gas source requirement: Nitrogen:99.999%

andInstall deoxygenation tubeBefore starting up, the carrier gas should be supplied for 2 hours with a flow rate of 80ml/min, and then the machine should be turned on for heating

6.Special reminder: First supply the carrier gas, then turn on the machine to increase the temperature!

【GC2020Characteristics of Gas Chromatography Instruments

◆Fully computerized button operation,5.7Large screen size13LCD Chinese display, human-machine dialogue mode, easy to operate.

◆New integrated digital electronic circuit, high control accuracy, stable and reliable performance, high-precision temperature control per second50Secondly, the accuracy can reach0.1℃.

◆Large column box volume:300*280*180， Maximize the capacity of multiple chromatography columns and two100rice0.53The capillary column.

◆Introducing foreign sample inlet designs to address sample discrimination; The dual column compensation function not only solves the program drift caused by temperature rise, but also reduces the influence of background noise, resulting in a lower detection limit.

◆Intelligent rear door opening system, dual door design, infinitely variable inlet and outlet air volume, shortening the stable balance time of the system after program heating/cooling; Heating furnace system: (temperature range) ambient temperature+5℃~400℃The temperature equilibrium time of the heating furnace is determined by the user.

◆Three injectors and three detectors can be installed simultaneously to solve complex sample analysis problems for customers.

◆Better insulation effect: column box, vaporization, and detection are all300When it comes to temperature, the outer box and top cover are the most hot spots40Improve experimental speed and ensure user safety.

◆Optional installation of automatic/Expansion devices such as manual six way injection valve, headspace sampler, thermal analysis sampler, cracking furnace, methane conversion furnace, etc., facilitate the analysis of special samples.

◆It has a power on self-test function, fault display, automatic protection, instant power-off protection, and strong anti-interference ability.

Excellent design concept:

◆Vaporization chamber design *, with smaller dead volume;

◆Easy replacement of accessories: the injection pad, liner, polarizing electrode, collection electrode, and nozzle can all be replaced with one hand;

◆Easy replacement of main body: filling column, capillary samplerTCD、FIDThe detector can be disassembled with just one wrench, making maintenance very convenient;

◆Excellent nozzle: * High temperature resistant quartz design, less prone to breakage and better inertness, rotating seal, better sealing *;

◆Reasonable positioning: * Capillary positioning system effectively ensures the repeatability of column installation and constant combustion rate;

◆Column head injection: Fill the column head injection to effectively prevent diversion discrimination effects.
